The spirit of fire had absorbed so much fire dragon grass at the beginning, and after refining it for nearly a month, it finally broke through, and it seemed to have reached the peak of the third change faintly.

"Well, I've just finished refining, but unfortunately I'm still close to breaking through the Yin and Yang realm. ”

When he came out, he saw the situation around him, and he was also surprised: "It's such a powerful seven-star core, and it has been burned into the formation, and the grade is already at the holy level, and the power is huge, so it's not a seventh-level force." ”

"It seems that this is the Tianhan Temple. ”

Sensing the surroundings, he also discovered Xu Yan's situation, and then he also closed his eyes, and then said: "The formation burned in this cave can communicate and even guide the energy of the star core to come out, you have such treatment, it is obvious that the Tianhan Palace is going to cultivate you." ”

Xu Yan nodded.

He knew that the reason why he had such a fast speed was because the cave had the ability to communicate with the star core, which was equivalent to you climbing a tree, and suddenly found that there was a staircase here, which could save a lot of effort.

However, this Heavenly Cold Hall is full of heritage, the energy of the star core is huge, even if you have a fast speed, you need to accumulate and polish for a long time, otherwise, there will not be so many people who will be in retreat for ten or twenty years.

Sensing the surroundings, he became more and more surprised: "These seven star cores, the peculiarities are different, but they are all very powerful, you look at the Heavenly Evil Star, the energy inside is full of evil energy, if it is absorbed and controlled well, it can make people's combat power soar, it is also a good situation."

Next, Xin sensed another star core, such as the northern pluto, which was full of dark and cold aura, although it was not very domineering, but it had a different taste, just like the feeling of freezing three feet and not a day's cold, far-reaching and unpredictable.

"Huh?"

At this moment, Na Xin suddenly said in surprise, his gaze looked at a star core that alternated red and white: "Strange, how can this ice Martian core give me a very familiar feeling." ”

It sensed it again, and found that there was a very special energy in it.

"Creation, this ice spark core, there is actually yin and yang qi, this is a good thing, the original void phantom demon flame was born in a place full of this energy, I can't imagine that there is still this kind of breath inside this star core. ”

As he spoke, he wanted to grab some, but then he found that there was a formation inside the star core, which isolated the grasping of the salary.

Xin frowned, and suddenly saw the futon where Xu Yan was sitting, and immediately flew there, sensed again, and finally grabbed a trace of green and white energy.

The energy, with its mysterious aura, flows gorgeously.

Xu Yan was originally surprised by what he had discovered, but when he saw this scene, his eyes were suddenly stunned: "This is no yin and yang?"

If he is not mistaken, this thing is almost exactly the same as when Yan Junyu got it, he didn't know what this thing was at the beginning, but now that he listens to what he says, he suddenly understands everything.

It's no wonder that the origin in his body will directly absorb that energy.

It turned out that the Void Phantom Flame was born in this energy.

"Yes, this is no yin and yang qi, no light, no landing, no contamination with any five elements energy, and it must be hidden in the void, it will take thousands of years to give birth to such a trace, but inside this star core, there are a lot of such energy, it is simply a miracle. ”

Xin praised and said: "However, these energies are isolated by the formation, obviously someone has discovered it, but as for whether anyone can absorb it, I don't know, however, according to some of my experience, this energy is not beneficial to the human body, and it will explode in special circumstances, which is very dangerous, obviously this Tianhan Temple does not have the strength to grasp things, so it will be isolated." ”

The strength of the salary was damaged, but the soul power was at least dozens of times that of Xu Yan, so if it wasn't for the salary just now, he wouldn't have felt it at all, and it would have been impossible for him to find out.

In addition, people whose souls exceed Xu Yan dozens of times are at least above the realm of Nirvana.

Therefore, the people of the Heavenly Cold Hall would not worry about the disciples absorbing those energies.

However, Xu Yan had the natal magic weapon of the Void Illusory Demon Flame in his body, but this was different.

At the beginning, he only absorbed a dozen wisps to make his body transparent, and if he absorbed more, maybe there would be some other means.

Of course, it would be better if you could urge the lifeless ladder.

It is said that all things are evolved from yin and yang, and that yin and yang are the mysterious energy that was born at the beginning of heaven and earth, and it is rare to see it later, and it is obviously only a few people who can master this yin and yang qi, or even no one at all.

And the subtlety of the world lies in the fact that the Void Illusion Demon Flame was born in it, so Xu Yan is now equivalent to indirectly mastering that energy and using it to urge the lifeless ladder.

Xu Yan tried to absorb that energy, and sure enough, as he expected, that origin absorbed the lifeless without any hesitation, and all of a sudden, Xu Yan and the inside of the star core seemed to have communication.

Moreover, faintly, Xu Yan felt that many changes were also taking place inside the lifeless ladder, and there seemed to be more aura, among which the fog began to be three times, revealing a brilliant gem, which gave people an extremely mysterious feeling, exuding colorful colors, giving people endless reverie.

In the blink of an eye, two months have passed, and Xu Yan doesn't know how much lifeless yin and yang qi he has absorbed, and today, the inner colorful gem of the lifeless ladder is finally hovering in Xu Yan's hands.

And as soon as his mind moved, his whole body was shrouded in brilliant colors, and his body was almost transparent, and no matter what attack he attacked, he could not be harmed.

"With the gem there, it's a defensive weapon that can withstand any attack. ”

Xu Yan was overjoyed, and even the salary was surprised: "I only know that this is the natal hair condensed by the Void Phantom Demon Flame later, but I don't know that there is such a thing in it, and now that you have this thing, it means that you can not be afraid of any attack." ”

Xu Yan nodded.

A month passed again, and this month, Xu Yan put all his mind on absorbing energy.

Of course, Xu Yan was also absorbing the energy of the Bright Sun Star, because, after all, this lifeless yin and yang qi was a secret, and he didn't want people to know, if it was discovered by the high-level of the Heavenly Cold Palace, there would definitely be unnecessary trouble.

At the same time, after a month of absorption, Xu Yan's arm also condensed an orange gem, which was exactly the same as Wu Han's original, but the color was different.

Through Wu Han's explanation, this thing can store mana, and it can also increase combat power at a critical time, and the more gems condensed, the more it will increase, and at the same time, it will represent the better the talent.

Because, the condensation of this gem has very strict requirements for the control of the soul, but Xu Yan's soul gathering technique is very clever, even in the Heavenly Cold Palace, it is also a more advanced existence than the ordinary Heavenly Rank Divine Power.

For example, those disciples on the steps need a little bit of fusion to absorb energy, and if they are not careful, they will let those energies slip away, while Xu Yan can directly turn the soul into a palm, directly capture it, and forcibly fuse.

Moreover, Xu Yan's soul origin, absorbing the spirit of gold, and the Void Phantom Demon Flame, can firmly suppress some energy, so if Xu Yan has time, he can condense more.

However, by this time, the three months had already arrived.

Xu Yan stood up, sensed the surroundings, and found that someone had already come outside the cave.

However, Xu Yan soon found a familiar figure.

"It's actually Wu Han and Deng Ba?"
